The flames burned increasingly lower down the slopes of the San Gabriel Mountains, threatening more than 2,000 homes in the La Canada Flintridge area. Fire burned right up to houses, but no structures were destroyed. At least 150 homes were under mandatory evacuation orders there.
More than 31 square miles of dry forest has been scorched by the fire, which continued to move out in all directions. Quintelier said the most active flanks are to the north, deeper into the forest, and east. The blaze was only 5 percent contained.
